A Conceptual Review of Identity Integration Across Adulthood

Though Erikson recognized identity development as a lifelong project, most research on identity has focused on adolescents and emerging adults. Less is known about how the identity formed in adolescenceis maintained and adapted across the adult life span. The purpose of the present paper is to providea conceptual review and elaboration of Erikson's (1968) theory focused on identity integration, aconstruct that is particularly relevant to adult identity development. Identity integration describes theprocess of bringing together various aspects of one's self into a coherent whole, and the sense of selfcontinuityand wholeness that emerges as a result of these processes. Informed by the identity and lifespan development literatures, we present a conceptual framework that describes how identity integrationis maintained across the adult life span, and how it is reestablished when changing life circumstancespresent threats to an individual's identity. These maintenance and reestablishment processes help to supportadults' well-being and adaptation to major life transitions and stressful events.
